Common questions about hvac installation costs, timelines, and what to expect.
Complete HVAC installation in Merrimack ranges from $7,000 to $15,000 for a mid-efficiency furnace and AC combination — typically an 80 percent AFUE furnace paired with a 14.3 to 16 SEER2 condenser. High-efficiency systems with variable-speed blowers and two-stage or variable-speed compressors run $12,000 to $22,000 but deliver significantly lower operating costs and qualify for federal tax credits. Heat pump systems fall between $5,000 and $18,000 depending on whether the system is single-stage, variable-speed, or a dual-fuel configuration. Ductwork modifications or new duct runs add $1,000 to $5,000. KIC Refrigeration provides detailed written proposals for Merrimack homeowners with every cost itemized and no hidden fees.
Yes, substantially. Replacing a 10 SEER air conditioner with a 16 SEER2 unit reduces cooling energy consumption by approximately 38 percent. Upgrading from an 80 AFUE furnace to a 96 AFUE condensing furnace saves 16 cents of every heating dollar — the old furnace sends 20 cents up the flue while the new one captures it. Combined with proper installation practices — correct refrigerant charge verified by superheat and subcooling, proper static pressure and airflow at 400 CFM per ton, sealed duct connections, and a programmable thermostat — a new system typically saves Merrimack homeowners $600 to $1,800 per year depending on home size, usage patterns, and local energy rates.
A standard furnace and AC replacement in Merrimack takes 1 to 2 days when existing ductwork, gas piping, and electrical service are adequate and the new equipment fits in the same location. A complete system replacement that includes ductwork modifications, new trunk lines, equipment relocation from basement to attic or vice versa, electrical panel upgrades, or zoning system installation may take 3 to 5 days. Multi-zone mini-split installations with 3 to 5 indoor heads typically take 2 to 3 days. KIC Refrigeration provides a clear timeline in every proposal, coordinates scheduling around your Merrimack home availability, and keeps you informed on progress every step of the way.
A properly installed and maintained HVAC system in Merrimack typically lasts 15 to 20 years for the gas furnace and 12 to 18 years for the air conditioner or heat pump outdoor unit. Variable-speed equipment tends to last on the higher end of these ranges because it runs at reduced capacity most of the time, causing less thermal and mechanical stress on components. The three biggest factors in equipment lifespan are installation quality, annual professional maintenance, and regular filter changes every 1 to 3 months. KIC Refrigeration offers maintenance plans for Merrimack homeowners that include seasonal tune-ups, priority scheduling, and repair discounts to help you get the maximum life from your investment.
